MODELS and RESULTS

Development of highly refined three-dimensional finite element model of the valve, seat and clapper had the main scope to obtain a reliable results at the clapper to valve seat connection.

Results in terms of equivalent plastic strain investigation along specified critical paths allowed to check that structural behavior meet the acceptable stress and strain limits proper of temporary loads as those acting on the valve.

AIM
Structural integrity assessment of seat valve under impact load due to valve clapper drop in order to guarantee the closure. The only reliable way to establish proper confidence over the valve structural behavior was the performing of an analysis by means of dedicated finite element model
